Subsequent requests for documents: process and significance in the award procedure
November 19, 2025
The subsequent request for documents is a central component of professional procurement procedures in which missing or incomplete documents are requested from bidders. This process ensures the completeness of the tender review and contributes to legal certainty. Find out below what the subsequent request for documents involves, which methods are used and how you can minimize risks.
Key Facts
- Legally permissible instrument for completing incomplete offers
- Must be offered equally and transparently to all bidders
- Time-limited by binding deadlines and award schedules
- Documentation required for the award file
- May only concern missing documents, but not incorrect content

Definition: Subsequent request for documents
The subsequent request for documents refers to the formal procedure in which contracting authorities request missing or incomplete documents from bidders in order to enable a proper tender evaluation.
Key features of the additional claim
The additional request only covers the completion of offers that have already been submitted. Strict legal framework conditions apply:
- Only missing documents may be requested subsequently
- Changes to the content of the offer are not permitted
- The principle of equal treatment must be upheld
- Transparency required for all bidders
Differentiation from other process steps
In contrast to renegotiation or bidder questions, the follow-up request serves exclusively to complete documents. It differs from the bid review in its active nature of information procurement.
Importance in the procurement process
The proper implementation of supplementary claims contributes to the legal certainty of the entire tendering process and minimizes the risk of bidder complaints or legal challenges.
Methods and procedures
The systematic implementation of subsequent claims requires structured processes and clear communication channels in order to meet legal requirements.
Structured reclamation processes
A standardized process ensures the proper handling of subsequent claims. Documentation in the contract award file is essential:
- Identification of missing documents during the tender review
- Written demand with a specific deadline
- Simultaneous information of all affected bidders
- Complete documentation of all communication steps
Communication management
Bidder communication in the event of additional claims must be transparent and comprehensible. Uniform deadlines and clear requirements must be defined.
Time management and deadlines
Adherence to the award schedule requires careful planning of the additional claim periods. These must be appropriately dimensioned and coordinated with the binding period for tenders.

Key figures for controlling subsequent requests for documents
Systematic key figures make it possible to evaluate the efficiency of reclamation processes and identify potential for improvement in procurement practice.
Process efficiency key figures
Measuring the rate of subsequent requests and processing times provides information on the quality of the initial service description and tender review:
- Claim rate per award procedure (target value: below 20%)
- Average processing time for subsequent claims
- Completeness rate after initial offer review
Quality indicators
The evaluation of the quality of the subsequent claim is carried out by measuring the success rate and legal certainty. Integration into the supplier evaluation scoring model is relevant here.
Compliance indicators
Legal certainty indicators measure compliance with procurement law requirements and minimize the risk of procedural errors. The quality of documentation in the procurement file is an important indicator in this regard.
Risk factors and controls for subsequent requests for documents
Improper subsequent claims can lead to legal challenges and procedural delays, which is why preventive measures and clear controls are necessary.
Legal risks and compliance
Exceeding the admissible additional request limits can lead to bidder complaints and procedural annulments. Particular caution is required when distinguishing between documentary additional requests and inadmissible bid amendments:
- Violation of the principle of equal treatment
- Impermissible influencing of the content of the offer
- Non-compliance with deadlines and procedural requirements
Process risks and quality control
Incomplete documentation or incorrect communication can jeopardize the legal certainty of the entire tender management process. Regular training and clear responsibilities are therefore essential.
Time risks and scheduling
Delays caused by extensive additional claims can jeopardize the entire award schedule. Realistic scheduling and buffer times are therefore important risk minimization measures.

Practical example
An industrial company is conducting a tender for IT services. During the tender review, it turns out that three out of five bidders have not submitted up-to-date reference documents. The awarding team requests the missing documents in writing from all bidders concerned with a deadline of five working days. It is explicitly pointed out that only the subsequent submission of references is permitted, not changes to the content of the tender. All communication is documented in the tender file.
- Equal treatment of all bidders through uniform additional claim
- Clear demarcation between document request and offer amendment
- Complete documentation for legal certainty
Current developments and effects
Digitization and new legal requirements are significantly changing the practice of requesting documents and creating new opportunities for more efficient processes.
Digitization of the subsequent claim processes
Modern electronic tendering platforms automate the identification of missing documents and standardize communication processes. AI-based systems can help to speed up completeness checks:
- Automatic completeness check of submitted documents
- Standardized demand templates
- Integrated deadline management and reminder functions
Legal developments
Current case law and new procurement guidelines specify the limits of permissible additional requests. This leads to a sharper distinction between permissible additional document requests and impermissible changes to tenders.
Increased efficiency through standardization
Companies are increasingly developing standardized catalogs of requirements and checklists in order to minimize additional requirements from the outset and speed up processes.
Conclusion
The subsequent request for documents is an important tool for ensuring complete and legally compliant procurement procedures. Companies can significantly improve the quality of their procurement processes through structured processes, clear communication and careful documentation. Digitalization offers new opportunities to increase efficiency, but still requires strict compliance with the principles of public procurement law.
FAQ
What may be requested in the event of an additional request for documents?
Only missing or incomplete documents that are required to evaluate the suitability or the tender may be requested. Changes to the content of the tender itself are generally not permitted and would violate public procurement law.
How long can deadlines for additional claims be?
The deadlines must be reasonable and allow bidders sufficient time to obtain the documents. Five to ten working days are usual, depending on the complexity of the documents requested and the remaining binding period for the bids.
Do all bidders have to be informed about additional claims?
Yes, the principle of equal treatment requires that all bidders are informed of any subsequent claims made. This can be done by means of anonymized notifications in order to ensure the transparency of the procedure and avoid legal challenges.
What are the documentation requirements for additional claims?
All additional claims must be fully documented in the award file. This includes the justification for the additional claim, communication with the bidders, deadlines set and the responses received for the subsequent traceability of the procedure.
